Scientists have developed the first functional pacemaker cells from human stem cells, paving the way for alternate, biological pacemaker therapy.

Researchers have invented a novel live-cell imaging method that could someday help biologists better understand how stem cells transform into specialized cells and how diseases like cancer spread. The Photonic Crystal Enhanced Microscope (PCEM) is capable of monitoring and quantitatively measuring cell adhesion, a critical process involved cell migration, cell differentiation, cell division, and cell death.

Building a realistic model of the human brain is a crucial part of understanding brain development, as well as neurological disorders such as Alzheimer's or Parkinson's disease. Using human stem cells, researchers have created a 3-D model of the human brain - and new research investigates how similar it is to a real brain.

Male hypogonadism is a condition affecting almost a third of the elderly male population. The most common treatment option is testosterone replacement therapy, but the practice can have significant side effects. A new development in stem cell research suggests an alternative treatment for hypogonadism may soon become available.

Single intracerebral doses of CTX-DP up to 20 million cells induced no adverse events and were associated with improved neurological function. Our observations support further investigation of CTX-DP in stroke patients.

German pharmaceuticals giant Bayer AG and U.S. health care investor Versant Ventures plan to establish a stem-cell research company, marking the latest effort by a big pharmaceutical company to develop new and innovative drugs by joining with venture capital and biotechnology firms.

em cells can develop into many different types of cells, such as muscle cells, red blood cells, or neurons. Given their special regenerative ability, stem cells can be used to treat a wide range of diseases. A team of researchers uncovers new details involved in the process of turning stem cells into motor neurons.

Pausing embryonic stem cells can be induced directly in cultured ES cells and sustained for weeks without appreciable cell death or deviations from cell cycle distributions.

The device consists of sensors encased in a flexible silicone shell and flanked on either side by electrodes. It sticks to the skin like a plaster or temporary tattoo and measures just 20 millimetres across.

A modified virus can repair diseased livers by turning bad cells into good. The treatment could one day offer a lifeline to thousands of people with liver failure.
